Jose Mourinho felt let down by Manchester United's players, accusing them of ignoring his advice and treating the Europa League clash at Fenerbahce like a "summer friendly".

Moussa Sow's outrageous overhead kick after 65 seconds gave Fenerbahce a lead that Jeremain Lens, on loan from Sunderland, extended with a superb second-half free-kick.
